To all whom it may concern? Be 1t known that I, ALBERT-D; ANDERSON,

a citizenof the United States, residing at I Dulutln in the county of St. Louis and State p of Minnesota have invented new Improvements in Seed-Dropping Meehaa .nism for Planters, offw'hich the following-is and useful a specification.

:This invention has relation to seeddroppin mechanisms for planters and it consists a I 1n the novel features and clalmed. I

" The ob ect of the hereinafter described invention is to provide a adapted to from a quantity of seed and drop the same singly at desired intervals. I

WVith this object in view the mechanism includes a hopper provided with a seed cup gravitate.- The hopper is mounted upon the frame of a planter and a suction cup upon the same. Means is provided for operating the suction pump at a desired rate of speed from the supporting wheel ofthe planter. A pipe is pivot'ally mounted upon the frame of the planter and is operatively connected with the said suction pump. ,The.

pipe is provided at one end with a cap have mg an opening shghtly less 1n dlameter than the diameter of the seed. This pipe is so arranged that as it swings upon its pivot the said cap is carried down into the seed cup and at the same time suction is created through the pipe whereby one of the seed is drawn againstthe edges of the opening in the cap. The pipe is then swung so that the cap is carried above and beyond the seed cap and at the same through the pipe is interrupted and a force draft is substituted said force draft being driven by the pump. This will thrust the seed away the seed is permitted to fall through a chute to the ground. The said pipe is also oper ated from the supporting wheel of the planter. v A i In the accompanying drawings Figure l is a side elevation of the seed dropping mechanism applied to a planter. The remaining Figs. 2 to 6 are detail views of the features of the device. I

'gThe planter to which the seed dropping mechanism is applied comprises a frame 1 which is mounted upon a supporting wheel 2 and which is also provided with handles 3.

of the 1 wheel 2 may is also mounted time the suction draft I from theopening in the cap and hracket 4: depends 'from oneh'of'the handles 3 and a shaft 5. is journaled at its forward end in the frame' l and at its rear ortion in the bracket 4. A' disk 6 is 'splined upon the shaft 5 and may be moved longiitudinally of the shaft. -The said disk 6 bears against the: side of the supporting 7 wheel 2 and is rotated by the said supporting wheel as'the planteris moved over the soil. A handle 7 iis slidably mounted in the frame 1 and engages the disk6and by moving the said handle 7 longitudinally the disk 6 may the said fromthe center thereof so speed at which the shaft 5'is rotated with .relation'to the rate of speed of the rotation be adjusted. Any suitable securing' means vas for instance that shown'at 8 maybe provided for holding the handle 7 at an adjusted position with rela- 'tion to the frame 1'. Ahoppcr 9 is mounted upon the handles 3 and is provided at one side and inthe vicinity of its lower end with a seed cup 10 into which seed may gravitate from the said hopper. Achute 11 is carried by the handles 3 behind the hopper 9 and thesaid chute is provided witha detachable cap or closure 12. A shaft 13 is journaled upon the handle 3 and is provided at one edge with a crank arm provided with a crank 15 and a pitman 16 operatively connects the crank 15 withthe crank arm 1%. pump cylinder 17 is piv= otallyconnected with the handles 3 and a piston 18 is slidably mounted in the said cylinder. A piston rod 19 is operatively connected with the said piston and at its lower end is connected with a bolt 20 which is adjustably mounted in a slot 21 provided in an arm 22 carried at the rear end of the shaft 5. A pipe 23 is fixed to the shaft 13 and a flexible tube or hose 2 1 connects one end of the pipe 23 with the upper end portions of the pump cylinder 17 A cap 25 is carried at one end of the pipe 23 and the Said cap is rovided with a relatively small opening 26.

The parts are so arranged that as the shaft 13 is rocked one end of the pipe 23 is dipped down in'tothe seed cup 10 and at the same time suction draft is created through the pipe 23 from the pump cylinder 17 in view of the fact that the piston 18 at 1 1. The shaft 5 is' be mov'edhalong the shaft wherebyv disk'may'be caused to contact with the wheel 2 at points more or less remote I that the rateof v been held by suction is forced away from the same and dropsv tion. Therefore the suction draft through the pipe 23 and the opening 26 in the cap 25 will draw one of the seeds "from the'cup 10 against the opening 26in the cup 25. After this takes place the shaft l3 rocks so that the cup 25 is carried up and away from the pump 10 but "remains over the upper end of the chute 11. When upon the return stroke of the piston 18 a forced draft is created in the-pump cylinder 17 the said blast :passes through the hose or tube 24 and pipe 23 and thus the seed which has. against the opening 26 down through the chute -ll to the round.

Therefore'it will be seen that seeds of'smalll This closure 12 is merely applied to the lower-end of the chute 1-1 when it is desired, todetermine whether or not the dropping. mechanism is dropping one seed only. By. applying the closure at such times and op-r i crating the device and thenexamining the number-of seeds which will be foundin the closure 12 at the end of each operation it,

is-accuratelydetermined whether or not the; mechanism is selecting theproper or desired;

.number ofseeds. v

Having described theinvention what is claimed is L-In combination with a seed receptacle up and means for operating the pump and for rocking the shaft.

2. In combination with a seed receptacle 'a'seed dropping mechanism comprisingv a fshaft journaled adjacent the receptacle, a seed pickup carried by the shaft, a pump pivotally mounted adjacent the shaft and operatively connected with the seed pickup a supporting wheel for the receptacle, a shaft journ'aled adjacent, the supporting wheel and operatively'; connected with the first mentioned shaft and the pump and a disk slidably mounted upon the last men- 'tioned shaft and having frictional engagemenHvit-h the said supporting wheel.

,3. In combination with a planter having :a supporting wheel, a hopper and a chute, a

: pump mounted upon the planter, a seed. ipickup mounted upon the planter and.

'adapted'to move from the receptacle to the ichute, means for operating the seed pickup lfrom the said supporting wheel and adjust- !able means for operating the pump from the h supporting wheel.
